Amount of money Ann earned this week = Amount of money earned in 1hour × Number of Hours she worked
Amount of money Ann earned this week = (4x + 3) × (2x - 1)
= (4x + 3) (2x - 1)
{Draw lines like rainbows to let yourself know which numbers to multiply by}
= (4x × 2x) + [4x × (-1)] + (3 × 2x) + [3 × (-1)]
{Always remember to put in the negative signs if the number if negative}
= 6x^2 + (-4x) + 6x + (-3)
= 6x^2 - 4x + 6x - 3
{Simplify}
= 6x^2 + 2x - 3
Answer:
Approximately 22,000 metric tonnes of fish per year
Explanation:
From the graph,
Rate of decline :
(metric tonnes of fish in 1965 - metric tonnes of fish in 1995) / range of years
(700,000 - 40,000)metric tonnes ÷ (1995 - 1965)
660,000 metric tonnes ÷ 30 years
660,000 / 30
= 22,000 metric tonnes per year
Approximately 22,000 metric tonnes of fish per year
